What can const variables not be used for?

To create constant pointers.
As rvalues in expressions.
To take their address in operations.
To modify once initialized.

The correct answer is: To modify once initialized.

Const variables cannot be used for modification once they have been initialized. This means that options A, B, and C are incorrect because they all involve actions that alter or modify the original const variable. Creating constant pointers, using the variable as an rvalue in expressions, and using the variable's address in operations all involve changing the value of the const variable, which is not possible.
